One hundred and seventy-two competitors of the Swiss Alpine Marathon, Davos, Switzerland, 1988, volunteered for this research project. Of these volunteers 170 (158 men, 12 women) finished the race (99%). The race length was 67 km with an altitude difference of 1,900 m between the highest and lowest points. Mean age was 39 (SEM 0.8) years. Average finishing times were 8 h 18 min (men) and 8 h 56 min (women). Loss of body mass averaged 3.4% body mass [mean 3.3 (SEM 0.2)%; 4.0 (SEM 0.4)%; men and women, respectively]. Blood samples from a subgroup of 89 subjects (6 women and 83 men) were taken prior to and immediately after completion of the race. Changes in haemoglobin (9.3 mmol.l-1 pre-race, 9.7 mmol.l-1 post-race) and packed cell volume (0.44 pre, 0.48 post-race) were in line with the moderate level of dehydration displayed by changes in body mass. Mean plasma volume decreased by 8.3%. No significant changes in plasma osmolality, sodium, or chloride were observed but plasma potassium did increase by 5% (4.2 mmol.l-1 pre-race, 4.4 mmol.l-1 post-race). Mean fluid consumption was 3290 (SEM 103) ml. Forty-three percent of all subjects, and 33% of those who gave blood samples, complained of gastro-intestinal (GI) distress during the race. No direct relationship was found between the quantity or quality of beverage consumed and the prevalence of GI symptoms.(ABSTRACT TRUNCATED AT 250 WORDS)

The role of human pancreatic-polypeptide in endocrine tumours of the pancreas is reviewed. Pancreatic-polypeptide may be involved in 3 different ways: 1. In cases with pure PP producing tumours. 2. In mixed endocrine tumours containing PP cells. 3. In cases with PP cell hyperplasia in normal pancreatic tissue associated with endocrine pancreatic tumours as VIP-omas, insulinomas, and glucagonomas. PP does not seem to serve as a general marker for endocrine tumours of the pancreas, but PP determinations are useful in patients wbith watery diarrhoea syndromes, because such syndromes may be associated with tumours that contain PP cells. Large molecular forms of PP occur in plasma from patients with endocrine tumours and high PP concentrations, but may also be found in other groups of patients. It is suggested that an atropin-suppression test could be of diagnostic value in revealing patients with increased serum concentrations of PP from other causes than vagal stimulation of normal PP cells.

A 57-year-old male patient with metastasizing non-beta islet cell carcinoma of the pancreas is described. Both gastrin and VIP levels were elevated and the patient suffered from a syndrome of pancreatic cholera and hyperacidity. The tumour contained gastrin and VIP as demonstrated by immunofluorescence. The patient also had a history of familial renal stone formation and parathyroid nodular hyperplasia. Resection of pancreatic tumour in 1973 resulted in four years without symptoms. In 1977 definite signs of multiple hepatic metastases appeared. These signs disappeared after streptozotocin given in a dosage of 2 g three times at weekly intervals. The patient had remained well for 20 months after this treatment. The causative agents for the clinical syndrome in this case are discussed in view of circulating hormone levels.

Within a ten-year scan (1967-1976) 207 insulinomas, 50 gastrinomas, 8 Verner-Morrison tumors, 5 glucagonomas and 12 endocrine pancreatic tumours with associated MEA syndrome (multiple endocrine adenomatosis) were treated surgically at various university hospitals (information obtained by questionnaire). Half of the insulinomas were treated by enucleation, one third by resection of the tail of the pancreas. Total gastrectomy was the procedure of choice in 80% of patients with gastrinoma, but sometimes pancreatic resection to remove the tumour was added. An new therapeutic concept of using histamine-H2 receptor antagonists for treating patients with Zollinger-Ellison syndrome is discussed. In the eight patients with a Verner-Morrison syndrome removal of the tumour or distal pancreatic resection was the procedure of choice.

Results of light and electron-microscopic studies of primary pancreatic tumor and of metastasis in a new case of Pancreatic Cholera (P.C.) are reported. The primary tumor but not the metastases, contained unusual, large cystic glandular formations, lined both by pancreatic-duct- and small-intestine-like epithelia and closely connected with the endocrine proliferation. A part from a few D-cells, the endocrine tumoral cells could not be identified by histochemical stainings. Their ultrastructural pattern, with small secretory granules (diameter less than 300 nm) and numerous cytoplasmic bunches of filaments, was very similar to that of gastric and duodenal D1-cells. Normal duodenal D1-cells have been said to produce gastric inhibitory peptide, a substance structurally and biologically similar to the vasoactive intestinal peptide actually secreted by the tumor. The normal histological appearance of gastric, gallbladder, jejunal, ileal, right and left colonic mucosae is consistent with the responsibility of the tumoral secretion in the impairment of gut functions in P.C.

The neurosecretory cells of the hypothalamus, and the cells of the pituitary gland and the pineal, are here grouped together as a central neuroendocrine division of the APUD series. The larger, peripheral division comprises the remainder of the original series. All the cells are proven or presumptive derivatives of neuroectoderm so that, with the present exception of the parathyroid gland and its products, peptide hormone endocrinology becomes neuroendocrinology. It follows that the pathology of the APUD cell series must be regarded as neuroendocrine and it is suggested that it can best be expressed by the term neurocristopathy (Bolande, 1974). Tumours of the series, properly neurocristomas, are preferably called apudomas because their common cytochemical (APUD) and ultrastructural characteristics provide the pathologist with a ready means of diagnosis.

In a healthy subject infusions of either secretion or glucagon caused no diarrhea. A combinations of gastrin and glucagon induced severe watery diarrhea immediately after the end of the 3 hour infusion. No diarrhea occurred from the combination of secretin and gastrin.
